Climate of the upper atmosphere
Abstract
<p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 9.0px Times;">In the frame of the European COST 296 project (Mitigation of Ionospheric Effects on Radio Systems, MIERS)</p> <p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 9.0px Times;">investigations of the climate of the upper atmosphere have been carried out during the last four years to obtain</p> <p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 9.0px Times;">new information on the upper atmosphere. Mainly its ionospheric part has been analysed as the ionosphere</p> <p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 9.0px Times;">most essential for the propagation of radio waves. Due to collaboration between different European partners</p> <p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 9.0px Times;">many new results have been derived in the fields of long-term trends of different ionospheric and related atmospheric</p> <p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 9.0px Times;">parameters, the investigations of different types of atmospheric waves and their impact on the ionosphere,</p> <p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 9.0px Times;">the variability of the ionosphere, and the investigation of some space weather effects on the ionosphere.</p> <br />
